如何使用IronPDF在 C# 中將 URL 轉換為 PDF（HTML轉PDF完整指南）

using IronPdf;

// Instantiate Renderer
var renderer = new ChromePdfRenderer();

// Create a PDF from a URL or local file path
var pdf = renderer.RenderUrlAsPdf("https://en.wikipedia.org/wiki/Main_Page");

// Export to a file or Stream
pdf.SaveAs("url.pdf");
